Tardigrade Admin · Accepted Answer

For isotonic solutions, π1=π2 i 1 C 1= i 2 C 2 (∵ constant temperature) ∴ 2 × 0.5=1 × C 2 C 2=1 M 1 molar aqueous solution of urea =60 g of urea in 1000 mL of solution =6 g urea in 100 mL solution =6 % W / V aqueous solution of urea

Q. $0.5 M N a Cl$ aqueous solution is isotonic with______ $%$ W/V aqueous solution of urea.
(Molar mass of urea $= 60 g m o l^{- 1}$ )

For isotonic solutions,
$π_{1} = π_{2}$
$i_{1} C_{1} = i_{2} C_{2}$
( $∵$ constant temperature)
$∴ 2 \times 0.5 = 1 \times C_{2}$
$C_{2} = 1 M$
$1$ molar aqueous solution of urea
$= 60 g$ of urea in $1000 m L$ of solution
$= 6 g$ urea in $100 m L$ solution
$= 6% W / V$ aqueous solution of urea

Q. 0.5MNaCl aqueous solution is isotonic with______ % W/V aqueous solution of urea. (Molar mass of urea =60gmol−1 )

For isotonic solutions, π1​=π2​ i1​C1​=i2​C2​ (∵ constant temperature) ∴2×0.5=1×C2​ C2​=1M 1 molar aqueous solution of urea =60g of urea in 1000mL of solution =6g urea in 100mL solution =6%W/V aqueous solution of urea

Q. $0.5 M N a Cl$ aqueous solution is isotonic with______ $%$ W/V aqueous solution of urea.
(Molar mass of urea $= 60 g m o l^{- 1}$ )
